Photosynthetic Bacteria that use sunlight to fix CO2 to organic carbon under anaerobic conditions, wherein, ferrous iron is the electron donor (Ehrenreich and Widdel, 1994). And those who produce their own food are producers and when (under certain conditions) they depend upon organic matter for their nutrition they are called consumers. Few group of photosynthetic Bacteria are primarily producer, where as a certain group hold the title of both producer and consumer.
Photosynthesis is the process that the Producers undergo to produce food for them and feed the Consumers. Producers are living things that can make their own food using air, light, soil, and water. Plants use a process called photosynthesis to make food. Only plants can produce their own food. That's why they are says producers. Through a process is photosynthesis, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels. Unlike producers, they cannot make their own food. To get energy, they eat plants or other animals, while some eat both. With just a few exceptions, all life on Earth depends on the sun's energy for survival. Producers make food for the rest of the ecosystem through the process of photosynthesis, where the energy of the sun is used to convert carbon dioxide and water into glucose.In plants and algae, photosynthesis takes place in organelles called chloroplasts. A typical plant cell contains about 10 to 100 chloroplasts. The chloroplast is enclosed by a membrane. This membrane is composed of a phospholipid inner membrane, a phospholipid outer membrane, and an intermembrane space. Photosynthetic bacteria, most commonly cyanobacteria, are important primary producers in tidal flats and salt marshes. Deep-sea ecosystems depend on primary producers that harness chemical energy from inorganic molecules such as hydrogen sulfide. Producers, who make their own food using photosynthesis or chemosynthesis, make up the bottom of the trophic pyramid. Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores. A producer is an organism that creates its own food or energy. A consumer is an organism that gets its energy by eating plants or animals. Producers, also called autotrophs, include plants, bacteria, and algae.Within the prokaryotic domain, there are five main groups of bacteria that perform tetrapyrrole-based photosynthesis. They are proteobacteria, heliobacteria, Chloroflexi, Chlorobi and cyanobacteria.
Photosynthesis is primarily carried out by producers, which are typically green plants, algae, and some bacteria. These organisms are capable of converting sunlight, carbon dioxide, and water into glucose (a sugar) and oxygen, using the process of photosynthesis.
Consumers, on the other hand, are organisms that obtain energy by consuming other organisms or organic matter. They include animals, fungi, and some bacteria. Consumers cannot perform photosynthesis.
Bacteria that perform photosynthesis, such as cyanobacteria, are considered primary producers because they can produce their own energy through photosynthesis. They are capable of converting sunlight into chemical energy, just like green plants and algae.

Primary consumers, mostly herbivores, exist at the next level, and secondary and tertiary consumers, omnivores and carnivores, follow. Land plants, or autotrophs, are terrestrial primary producers: organisms that manufacture, through photosynthesis, new organic molecules such as carbohydrates and lipids from raw inorganic materials (CO2, water, mineral nutrients). Primary consumers are normally herbivores. They are also referred to as heterotrophs as they don't produce their own food. They largely rely on autotrophs, which are plants that produce their food through photosynthesis. These organisms use several other feeding strategies. Some bacteria, such as cyanobacteria and purple and green sulfur bacteria, engage in photosynthesis. Since bacteria don't have chloroplasts, photosynthetic pigments are found in their membrane folds. Sunlight supports the photosynthetic process used by producers whereby heat disperses into the atmosphere and oxygen is produced. Consumers use this oxygen and feed on the food provided by producers and give off heat and carbon-dioxide as they do so. Carbon dioxide plus sunlight forms the food of the producers. Plants are autotrophs, which mean they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels. Plants, blue-green algae, as well as some bacteria like purple and green-sulphur bacteria, perform photosynthesis. Photosynthesis occurs only in some bacteria such as cyanobacteria, which is a diverse group of cyanobacteria. They are also known as blue-green bacteria. In higher-order plants, photosynthesis occurs in the chloroplast.
